Advantage is a wonderful clause in the rules in which whistling the foul would actually be hurting the team being fouled by not letting play continue. Let's say the white midfielder is dribbling the ball outside the gray penalty area when a gray player pushes white. Yet white does not fall down and is still able to continue the dribble unimpeded toward goal. The ref yells "Play on!" with both arms extended, indicating to everybody that there's an advantage.

The teams spend time training and working on teamwork in practice. Their coaches go over tactics before the game. Doesn't it logically follow that the officiating team needs to spend some time before the game discussing how they will work as a team?
